Do I need to
apply PenaShield to both sides of the wood?
Apply PenaShield to all four sides of the wood whenever
possible. Treat the wood twice if access to only one or
two sides of the wood is available. Read and follow all
label instructions before use.
How long will it last?
When protected from the weather because the wood is indoors,
PenaShield will last for the life of the wood. If coated
with a water repellent finish, PenaShield will last as long
as the water repellent is maintained. If outdoor wood is
not sealed or painted, additional PenaShield applications
will be needed every 1-5 years.
